ridiculous battery drain during night/stand-by

hey guys.
lately my Hero seems to be draining battery like crazy at night when the phone is on stand-by. i have the villainrom 10.3 ROM installed, and during the night the only app that was running was "clock". no wifi or mobile network turned on, no GPS etc, and were talking 45-50% battery drain for 8 hours with the phone in stand-by.
why is this happening?

I had the same problem yesterday. In 5 hours my battery drained 80%, so I closed all the apps that was running, but still no change. I then restarted my phone, and after that, it looks normal, but will update if it does it again.
Hope someone has an answer...

Firstly, have you recently flashed a rom and when doing so hard your phone on charge?
If so you will need to run a procedure to reset your battery.
Either
Discharge down to around 5%, go into recovery wipe batt stats, then charge to full with it powered off
or
Charge to full with power on, then power off and charge until green light again. Then wipe batt stats and boot and continue normally.
If you have not flashed a rom recently then this is unlikely to be the issue and something else will be draining your power, e.g. an infinite sync?

Thanks, will try that

thanks lenny, yeah i recently flashed to villainrom but i do believe the problem started a few days prior to it, will try to reset the battery.
how can i check the infinite sync problem?

either by reading a logcat or checking to see if the sync icon is always on and never seems to go away.
Best practice is to untick everything you don't need to sync in the sync menu.

Allrightyroo, I don't see the sync icon and I think all the syncs I do are manually. Did the battery wipe now, I'll see if it helps.
Btw, is there any difference in charging thru USB or wall socket? I might be biased but I feel I get better battery performance when charging with wall socket..

It will charge quicker from a wall socket but it won't be any better.

Well, I've tried everything but it still drains up to 50% battery during the night, avg. 8 hrs or something. Have turned off background data and sync, wiped battery stats, recharged the way Lennyuk explained etc etc.
what the hell is wrong? My Hero is unusable if I have to charge it as often as this.

Reflash / change ROM.
And about USB or wall socket. There is big difference. USB gives only 500mA, when the wall socket gives is 1000mA. Feel any difference? Do not charge you battery by USB too often.
P.S.
Check with task killer whats on when you go to sleep. Try to kill tuchflo before standby.

Charging through a wall socket makes no difference other than it will take long to charge via USB

Well, IMHO there is difference, because of we have double ammount of ampers, with the same voltage. Charging with USB is slower, and may charge battery not to 100% (even if phone is saying it is 100%). Ofcourse it will not damage your battery if you use USB.

i had this problem prior to flashing to VillainROM 10.3, i used Modaco 3.2 up until then. checked my taskkiller and nothing was using battery other than "clock".

Do you have the calender widget on your home-screen? That widget is draining the battery like hell. Had also the same problem after i've added the calender widget to my homescreen.... after removing it, everything was normal.

yes i do actually, will remove it and see if there's a difference.

Try removing auto-sync or the calendar sync because if i remember well there is an issue with that with a few roms..

Removed the widget and had 54% battery for atleast two hours now, seems to be the root of the problem.
Can someone explain the uptime and awake time? When I checked my Hero this morning after 9hrs of sleep it said
Up time: 20h 48 min
Wake: 2h 39min
and this is without touching the phone for 9 hrs.

I'm interested as well. Where do you remove calendar sync? I could only find the Google calendar sync, and unticking it didn't change anything. Calendar still appears in Spare Parts on Partial wake usage.

Up time is the time the phone's been on.
Wake time is the time when you have been using the phone (screen on). When you turn the screen off, wake time should stop until you turn the screen on again. If wake time still goes up even when the screen's off, then there must be some application preventing your phone from sleeping.

Yeah, and that is kinda strange since "clock" was the only open application during that period. What does it say on your Heroes when you press the sleep button and then wake it up and check battery stats? 10 sec?

I was going so far because of this problem, that i asked htc about a new battery, after i told them that the calender was the source of this problem i asked if they will update it, but i didn't got a clear response... in the end in the response was nothing standing... well maybe they got it with the 2.1 update

Broken battery?

Hi!
I'm suffering from a strange battery behavior lately: This morning, after 9 hours charging, I woke up to a 75% full battery, when usually, it should get 100% charge overnight. Previously, I had an accidental power off by power depletion, some hours ago.
Now, I'm trying to charge the phone but it seems to charge way too slow.
Finally, I decided to power it off and let it charge without any possible drainage. In the moment I powered it off, I was prompted with the battery icon displaying 96% charged...??!?!?!?
I don't know if either the battery is broken, the rom is reporting it wrong or what.
I usually play Ingress, which drains the battery like crazy, and I'm usually browsing the internet and reading twitter on my phone, so, at the beginning I thought I just needed to keep my hands off the phone for a while and let it charge, but after that overnigt 75% charge incident... I don't know what to think.
ROM is Carbon ROM KK, kernel is AK without any tweaks, no undervolting or anything... any advice?

Don't over charge.

Yes, I have the bad habit of being unable to see my phone drop the battery level under 60%. At my job, I always leave it on a qi charger, regardless of it being full or empty. Perhaps I have to take the habit of letting it drain until 30% or so, and start charging then.
Other thing I can do is limit the charge level top, tweaking the kernel setting via synapse..... Could that be a good thing?
After starting the phone, the battery level seems to be OK. It's 87% now and it's draining quite slow, compared to before. I guess I'll have to start treating my battery better.

Some update: the phone was bought on March 2013,but the battery has a build date of December 2013. I think the guys that repaired the phone swapped the battery for another one and left me with a defective one.

qpnp-smbcharger-ffffffc00ea20400 wakelock issue

Subject of this thread is listed as a major kernel wake lock at times for me. Anyone know exactly what that is?

I just started seeing this wakelock also. I haven't changed anything lately and it just appeared. I hope someone has an answer.

I just started getting it since updating to 6.0.1 PN. I switched to AK Synapse and it drastically reduced it, but it is still there. Only info I can find is much older phones. I am using an LED manager...wonder if that could be it. May freeze it this week and see.

I believe that wakelock is from charging. I don't know why but the device doesn't seem to register as deep sleep with better battery stats when fully charged and then idle but still plugged in. Likely an issue with the program and not the phone.
However if you want to test this simply charge your phone over night. Once it hits 100% it will stop charging at some point and go into sleep mode. The device is still plugged in but won't charge anymore. Device will use power, mine is usually around 95 or 93% when I fire it up and use a little juice in the morning. During this time the device uses battery quickly until it drops to 89% or so then normal discharge rate. This is normal of most android devices I've had and most everyone here is aware of this:
http://phandroid.com/2010/12/25/you...is-lying-to-you-and-its-not-such-a-bad-thing/
Getting back to the wakelock issue, f you check better battery stats this wakelock shows up under the above condition. You'll notice the time on this wakelock is usually the sum of the device on but screen off time and your screen on usage or pretty close to it.
Now charge your device to full while waiting for it (as in not going to leave it for 4+ hours on the charger after it is full). Once it stops charging at 100% pull the device. Use as normally.
Now the device is fully charged. Really this time and not just the UI telling you it's full. When you use it throughout your day and then check better battery stats you'll notice the wakelock is no longer there or nearly so depending on how fast you got the device off the charger after it was full.
End result is this seems like a reporting issue with better battery stats or the device not fully going into deep sleep while being plugged in. I would tend to lean on a reporting issue as discharge time seems about normal at 1% or so per hour while idle and that tends to hold true to my regular doze discharge.
TLDR:
This seems more like a reporting issue than actual wakelock. Any significant battery drain when fully charged can be explained by the link above and testing as I have explained in the post.

The only thing is this wakelock doesn't start until after I unplug it and leave for work. It grows during the day..so is it faulty reporting? Something is using my phone when idle for about 2 hours a day with screen and sync off at 384 Mhz and that wakelock usually shows at about an hour and 10 minutes or so. I have also done as you said and after it dropped to 97% charged it back up and pulled it off immediately..same wakelock and similar time. Also this wakelock was not there with 6.0.0. So Google changed something with 6.0.1 that brought this to life for me. Also interestingly, this wakelock was at about 4-6 hours with stock kernel. I changed to AK kernel and that is what made it drop to about an hour and doubled my standby time.

OK, I froze Light Manager with TB and this wakelock went away. This was the only new thing I added to 6.0.1 to get the battery fully charged light to not change until 100%. Stock changes it at 90% for some stupid reason. So if anyone is using an LED manager, try removing it for a day and see if that makes this wakelock go away.

so here is the source. Are you guys all using the stock charger that came with the device? Only reason I ask is because I didn't start seeing this until I started using a samsung charger with a micro to c adapter.... I think

Reported at 93% it's my highest wakelock. Stock charger and no LED manager installed. Other causes or fixes?

I too have this at the top of my wakelocks. Did anyone else find a solution? I don't have any led managers

I contacted Lenovo support on email. As usual they told me to do FACTORY RESET. I did factory reset but eventually after couple of days issue started again.
there is some issue with SMB1351 chip on motherboard of Lenovo P2. but they are not able to figure it out. In battery stat, there is no issue with any of the apps which i installed on my phone.

Phone stays awake after being taken off charge

Hi there
Topic says it all.. when I take the phone off the charger after it has got to 100%, it will stay awake until I start using the phone.
This might sound insignificant, but I normally charge my phone at night - and if I wake up at say 2am and it's charged I just unplug it. The next time I use the phone around 7am, the battery will be down to 93% or something. This is because the phone remains awake for this 5 hour period.
As soon as I start to actually use the phone, it will begin to sleep as normal. I know phones stay awake while on charge so it's almost like this continues when unplugged. Has anyone else noticed this or can someone test to see if theirs does the same? Basic test is:
1) Charge to 100%
2) Unplug ONLY - don't unlock the phone
3) Leave it idle for 30 mins
4) Check the battery stats
Phone is on stock NPN25.137-33
Thanks
James

I can confirm this.

When you check the battery stats, what thing consumes the battery there?

It will just say "phone idle" which is absolutely useless. I'm not rooted so trying to find a wake lock is more difficult... my guess is it would just classed as a charge wake lock even though the phone is unplugged.

Battery Health or Seemingly Random Drain off the wall

Hey all
I've noticed something of late with my OP6T. When I charge it to 100% and take it off the charger, it drops ~5% very quickly seemingly without any wakelocks/alarms that cause it. Does anyone else experience this? Is there something I can do about this or is the battery just on it's way out? It's a little strange as the device is only 1yr old. I bought it around 9 Nov.
Here are some of the screens from BBS attached. As you can see it doesn't look out of the ordinary.
Another strange thing is that once it reaches around ~95% then it will start to act as normal, so it takes MUCH longer to go from 95 downwards.
What's going on here?
Other things tried:
- root and run battery calibrate
- factory flash fastboot images
- use custom kernel
All show the same issue so far. This did not happen at all until recently. Any help would be appreciated!

UPDATE: I let the battery drain completely and had the phone self-power off, then powered it up a couple more times until the "Battery too low, charge before use" sign started coming up. Once that happened, I plugged the phone into a slow charger, turned it on and left it to charge. I plugged it out when I went to bed (at 100%) and it seems to be all good now. Woke up 6 hours later with the phone at 98%.
Just in case anyone else is having the issue, give that a try.

Battery percentage is a estimate. Discharging it fully and charging it only makes the estimate a bit more precise. I remember on my old phone that it could drop 40 percent in 15 minutes and when you put the device away in your pocket it could go up about 5 percent.
